Sanjay Leela Bhansali is just not interested in repeating his past mistakes. The filmmaker has preponed the release of his upcoming film 'Bajirao Mastani' to 18th December. This way Bhansali has averted a clash with the Shah Rukh Khan starrer 'Dilwale'. Earlier both 'Bajirao Mastani' and 'Dilwale' were scheduled to hit the theatres on the same date i.e 25th December. The director and actor had clashed last time in 2007 when both 'Om Shanti Om' and 'Saawariya' were released on Diwali, but the ego of Sanjay Leela Bhansali consumed the life of 'Saawariya' at the box office.
